ping `and skidding as well as increasing the ground` action qualities of the wheel.

A further object is to provide a non-skid plate having a tread surface positioning spiral bars and coil springs each lying longitudinally of the tread and alternating with one another, the spring members being replaceable.

A still further object is to provide a nonskid element adapted tobc secured in any desired numbers and distances apart to the tread portion of a wheel', each rovided with a metallic gripping tread' and positionable upon the wheel encircling the tire and folly thereof.

lVith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of arts hereinafter' fully described, illustrated) in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :fFi ure 1 is a side elevation of a portion of a 'w ieel pro- Fig. 2 is a' transverse sectional view of Fig. l taken. upon line. 2-2 of Fig. 1. Fig. 3 is an enlarged lan view of a section of the tire and the evice thereon. Fig. L1 is a detail sectional view taken upon line l-*et of Fig. 5l in the direction indicated by the arrows, the spring however, being in side elevation, and, FigI 5 is a similar sectional view taken upon line 5-5, of Fig. 3 as indicated by the arrows.

Referring more in detail to the drawings, it is designed to provide a pad of heavy leather or similar material 1() positionable upon the tire as 11 and having a metallic Specication of Letters Patent.

plate 12 of slightly less dimensions and seated upon the outer surface of the pad and encircling the tire, both of said plate and pad being )rovided with slots 13 at their opposite ens, in which are positioned links 14 for the reception of straps 15 which are secured therebetween and provided with buckles 16 to be'clasped adjacent the lower side of the rim or felly 17 of the wheel for locking the combined plate and pad u on the tire. The opposite edges of the p ate are uptnrned in the form of opposite parallel marginal tia-n es 18 while spiral metal Ibars 19 are llaty secured between said `flanges upon the plate and .positioned lon'- gitudinally of the tread portion thereof for positioning longitudinally of the tire when the device is in position thereon. Said flanges are provided with opposite perforations 20 for receivin the hooked ends 21 of closely coiled helica springs 22 whereby said springs are secured, bowed slightly outwardly, between each two ad'acent ones of the bars 19 and lying parallel to said bars, these springs being likewise positioned longitudinally of the tread portionl of the plate an'd tire.

The complete operation of the devicewill be apparent from the above detailed description in that the devices being furnished in any desired numbers, the same upon removing the stra `s 15 are readily applied around the tire an( the strips then employed for securing the device 1n place thereon and with the longitudinal tread members consist ing of the spiral bars and intermediately positioned coils. Such devices being' attached to the tire and preferably positioned between the wheel spokes 23 as shown in Fig. 1, the tread of the tire is provided at. intervals with the ground traction surfaces, while the springs 22 may be readily removed and replaced when desired by unbending the hooked ends 21 thereof while such springs may be entirely eliminated if desired, it being also noted that the plates 12 are provided with cut-out portions or o en'ings 24 upon the opposite sides thereo which reduces their weight.

While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that various forms and modifications may be had without departing from the spirit and scope of the Y 'invention as claimed.

What is claimed as new iszl l. A device oi the class described, comprising a flexible ad adapted to encircle e tire and having s ot's adjacent its opposite ends, a. metallic plate seating upon said pad and having slots adjacent its ends registering with the slots 1n the pad, links positioned through said slots of the pad and plate,V straps extending through said links and secured around'thevfelly of the Wheel, u turned opposite parallel flanges uponr said p :ite having perforations therethrough, out- Wardly bowed helical springs secured in said Eerforations and positioned. in parallelism etween said flanges, and spiral metallic bars secured between said flanges alternating with said, springs and ila-ily engaging upon,

said plate.

2. A device of the close described; comprising e leather pad adapted to encircle a tire, a. metallic plete flatly positioned upon the outei1 surface of said pad, said g-:zd and plate provided with aliniug slots tlirough their opposite ends, links engaging' 'Within scid slots, links tid secured around said elly, cui War'dly projecting marginal flanges upon said plateaud Fpositioned at the 'treed por tion thereof, spiral metallic bars securedin fiat engagement upon said plate between saidthrough sid perforetions and positioned inv alternation with seid bars.
